I have a 2006 Jeep Liberty that has recently begun to have problems starting when the engine is still warm from driving. Letting it cool off for 10-15 minutes is usually enough to allow it to start.
The starter will crank and the battery is new, so it isn't an electrical issue.
When cranking, the tachometer does move so I suppose that means that crankshaft position sensor is working.
I've recently changed the coolant, water pump, and thermostat but that hasn't helped. Coolant temperatures seem fine while driving.
Attempting to start in "clear flood mode" (by holding the accelerator) also does not help, so it's not an issue of being flooded.
I've cleaned the intake air temperature sensor with some electrical cleaner, without any improvement. The MAP sensor was replaced a couple years ago (before this problem started), so I would expect it to still be good.
There are no check engine codes, and the engine has never stalled once it has started.
Does anyone have any other suggestions on other things I should investigate?
